Pink fairy armadillo that fits in your hand

Notebook A 001

This is a rarely-seen "pink fairy" armadillo that lives in western central Argentina. Chlamyphorus truncatus, the tiniest armadillo species on the planet, spends almost all of its time underground, making it hard for researchers to determine whether it's endangered or just very elusive. Scientists at Mendoza, Argentina's CONICET research center recently had the opportunity to study one in captivity and discovered that the animal doesn't "swim" through sand as previously suspected but rather "digs and then it backs up and compacts the sand with its butt plate."
